Description

Technical Field

[0001] The present invention relates to the technical field of quenching equipment, and specifically relates to a heat treatment quenching equipment for internal combustion engine rocker arms. Background Technique

[0002] After the internal combustion engine rocker arms are produced, they need to be quenched. Through quenching treatment, the rigidity, hardness, wear resistance, fatigue strength, and toughness of the internal combustion engine rocker arms can be greatly improved. When the internal combustion engine rocker arms are quenched, the rocker arms need to be fixed. Fixing the rocker arms can ensure uniform heating of the rocker arms during the quenching process, thereby ensuring the quality of quenching. However, when the existing internal combustion engine rocker arm quenching equipment quenches the internal combustion engine rocker arms, it is necessary to fix the internal combustion engine rocker arms one by one. Such an operation is very cumbersome and not convenient. It not only increases the work intensity of the staff, but also makes the work efficiency of fixing the internal combustion engine rocker arms relatively low, thereby affecting the quenching work efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a heat treatment quenching equipment for internal combustion engine rocker arms to solve the problems raised in the above background technique.

During the quenching process of the rocker arms, the limiting component limits the rocker arm support mechanism; A reset component is also arranged on the rocker arm support mechanism. When the rocker arm support mechanism moves outside the quenching furnace, the reset component drives the reset of the multi-rocker arm synchronous fixing mechanism to realize the synchronous unlocking of multiple rocker arms.

An activity channel is formed in the supporting arc plate, and a moving fit hole is further formed in the quenching bearing plate above the bearing channel; The moving fit hole is located in the activity channel, and a limiting vertical rod is fixedly arranged on the upper end surface of the quenching bearing plate.

[0008] Preferably, the multi-rocker synchronous fixing mechanism comprises a connecting load strip, a movable bearing block and an arc-shaped pressing strip. Movable insertion rods are symmetrically and fixedly arranged at both ends of the connecting load strip, and the movable insertion rods are inserted into the movable through holes; A fitting vertical frame is fixedly arranged at the upper end of the connecting load strip, and inclined reset frames are symmetrically and fixedly arranged on the fitting vertical frame.

[0009] Preferably, a bearing plate is further fixedly arranged at the upper end of the connecting load strip, a bearing fitting rod is fixedly arranged on the bearing plate, and the bearing fitting rod passes through the moving fit hole and is inserted into the activity channel; A supporting load block is fixedly arranged on the bearing fitting rod. Part of the supporting load block protrudes above the activity channel, and a pressing column is fixedly arranged on the supporting load block.

[0010] Preferably, a connecting convex block is further fixedly arranged on the connecting load strip. Movable connecting rods are symmetrically hinged at both ends of the connecting convex block, and the other ends of the movable connecting rods are connected with an arc-shaped pressing strip; A fitting sliding hole is formed at the lower end of the movable bearing block, a supporting bearing rod is inserted into the fitting sliding hole, and pressing strips are symmetrically and fixedly arranged at the upper end of the movable bearing block; Part of the pressing strips protrudes above the activity channel, and fitting connecting rods are symmetrically hinged at both ends of the movable bearing block. The other ends of the fitting connecting rods are hinged with the arc-shaped pressing strip.

[0011] Preferably, a mounting bearing plate is fixedly arranged at one end of the arc-shaped pressing strip. The mounting bearing plate is inserted into the bearing channel, and a limiting sliding hole is formed in the mounting bearing plate; A limiting bearing rod is inserted into the limiting sliding hole, and the mounting bearing plate is hinged with the other end of the movable connecting rod.

[0012] Preferably, the limiting component is a movable stop strip. Fitting stop strips are symmetrically and fixedly arranged at both ends of the movable stop strip, and the fitting stop strips are located below the inner supporting strip, A support connecting column is fixedly arranged at the upper end of the cooperating bar. A limiting top block is fixedly arranged at the upper end of the support connecting column. The support connecting column is inserted into the connecting cooperation hole, and the limiting top block is inserted into the storage hole.

[0013] Preferably, the reset assembly is a reset connecting bar. A limiting cooperation hole is formed in the reset connecting bar, and a limiting vertical rod is inserted into the limiting cooperation hole. Bending vertical plates are symmetrically and fixedly arranged on the reset connecting bar on both sides of the limiting cooperation hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, with the following advantages: 1. A quenching bearing plate is installed in the quenching furnace. A support arc plate is arranged on the quenching bearing plate. When quenching the rocker arm, the rocker arm is sleeved on the quenching bearing plate through the shaft hole and is located between a group of tightening columns and tightening bars. Then, further pushing the quenching bearing plate into the quenching furnace can achieve the automatic locking of the quenching bearing plate and the synchronous fixation of multiple rocker arms at the same time. The operation is simple, convenient and fast.

[0015] 2. When further pushing the quenching bearing plate into the quenching furnace, as the quenching bearing plate moves, the connecting carrier bar will contact the inner wall of the quenching furnace. Under the restriction of the inner wall of the quenching furnace, the connecting carrier bar will no longer move, and thus the distance between the connecting carrier bar and the quenching bearing plate will become smaller. Under the action of the movable connecting rod, the arc-shaped tightening bar will be pushed to move away from each other, and then the arc-shaped tightening bar will be tightened against the inner wall of the shaft hole of the rocker arm, playing a certain fixing role on it.

[0016] 3. In addition, as the quenching bearing plate moves, it will drive the rocker arm close to the tightening column. At the same time, as the arc-shaped tightening bar moves, under the action of the cooperating connecting rod, it will also drive the movable bearing block to move towards the rocker arm. In this way, the tightening column on one side and the tightening bar on the other side of the rocker arm can clamp and limit the rocker arm from both sides, further strengthening the fixation of the rocker arm and ensuring its stability. Moreover, as the quenching bearing plate moves, it will drive the reset connecting bar to move upward under the action of the inclined reset frame. When the quenching is completed, as the quenching bearing plate moves in the reverse direction, the reset connecting bar will move downward to reset under the action of gravity, thereby automatically unlocking the rocker arm, which is convenient for the staff to remove it without the need for the staff to unlock the rocker arms one by one.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The present invention provides a technical solution: As Figure 2 and Figure 3 shown, a heat treatment quenching device for an internal combustion engine rocker arm includes a quenching furnace 1. At both ends inside the quenching furnace 1, support inner bars 11 are symmetrically and fixedly arranged. A rocker arm support mechanism is installed on the support inner bars 11 to support the rocker arm and achieve the quenching treatment of the rocker arm. And a multi-rocker arm synchronous fixing mechanism is arranged on the rocker arm support mechanism. When the rocker arm support mechanism further moves into the quenching furnace 1, multiple rocker arms are synchronously fixed through the multi-rocker arm synchronous fixing mechanism. A limiting component is also installed on the support inner bars 11. During the quenching process of the rocker arm, the limiting component limits the rocker arm support mechanism. A reset component is also arranged on the rocker arm support mechanism. When the rocker arm support mechanism moves outside the quenching furnace 1, the reset component drives the reset of the multi-rocker arm synchronous fixing mechanism to achieve the synchronous unlocking of multiple rocker arms.

[0032] As Figure 3 and Figure 4 shown, an indentation bottom groove 12 is opened at the lower end of the support inner bar 11, and a receiving hole 13 is also opened on the support inner bar 11. A connecting and mating hole 14 is opened at the bottom of the receiving hole 13, and the connecting and mating hole 14 penetrates through the receiving hole 13 and the indentation bottom groove 12.

[0033] As Figure 1 and Figure 8 shown, the rocker arm support mechanism is a quenching bearing plate 2. Activity through holes 21 are symmetrically opened at both ends of the quenching bearing plate 2. Support vertical rods 22 are fixedly arranged on the quenching bearing plate 2 below the activity through holes 21. A moving support ring 23 is fixedly arranged at the lower end of the support vertical rods 22. The moving support ring 23 is sleeved on the support inner bar 11, and the inner wall of the moving support ring 23 is in contact with the support inner bar 11. The inner wall of the moving support ring 23 is smooth and free of burrs, and the surface of the support inner bar 11 is smooth and free of burrs.

[0034] As Figure 8As shown, a bearing channel 24 is further formed in the quenching bearing plate 2. A limiting bearing rod 25 is fixedly arranged in the bearing channel 24. A supporting bearing rod 26 is fixedly arranged on the quenching bearing plate 2 below the bearing channel 24. A supporting arc plate 27 is fixedly arranged on the quenching bearing plate 2 above the bearing channel 24. An activity channel 28 is formed in the supporting arc plate 27. A moving matching hole 281 is further formed in the quenching bearing plate 2 above the bearing channel 24. The moving matching hole 281 is located in the activity channel 28. A limiting vertical rod 29 is fixedly arranged on the upper end surface of the quenching bearing plate 2.

[0035] As Figure 2 , Figure 5 , Figure 6 and Figure 9 As shown, the multi-rocker synchronous fixing mechanism includes a connecting carrier bar 3, a movable bearing block 4 and an arc-shaped pressing strip 5. Movable inserting rods 31 are symmetrically and fixedly arranged at both ends of the connecting carrier bar 3. The movable inserting rods 31 are inserted into the movable through holes 21. A matching vertical frame 32 is fixedly arranged at the upper end of the connecting carrier bar 3. Inclined reset frames 33 are symmetrically and fixedly arranged on the matching vertical frame 32. The inner walls of the inclined reset frames 33 are smooth and free of burrs.

[0036] As Figure 9 As shown, a bearing plate 34 is further fixedly arranged at the upper end of the connecting carrier bar 3. A bearing matching rod 35 is fixedly arranged on the bearing plate 34. The bearing matching rod 35 passes through the moving matching hole 281 and is inserted into the activity channel 28. A supporting bearing block 36 is fixedly arranged on the bearing matching rod 35. A part of the supporting bearing block 36 protrudes above the activity channel 28. A pressing column 37 is fixedly arranged on the supporting bearing block 36. The pressing column 37 is located above the activity channel 28.

[0037] As Figure 6 As shown, a connecting convex block 38 is further fixedly arranged on the connecting carrier bar 3. Movable connecting rods 39 are symmetrically hinged at both ends of the connecting convex block 38. The other ends of the movable connecting rods 39 are connected to the arc-shaped pressing strip 5.

[0038] As Figure 5 and Figure 10 As shown, a matching sliding hole 41 is formed at the lower end of the movable bearing block 4. The supporting bearing rod 26 is inserted into the matching sliding hole 41. Pressing strips 42 are symmetrically and fixedly arranged at the upper end of the movable bearing block 4. A part of the pressing strips 42 protrudes above the activity channel 28. Movable connecting rods 43 are symmetrically hinged at both ends of the movable bearing block 4. The other ends of the movable connecting rods 43 are hinged to the arc-shaped pressing strip 5. In addition, the surfaces of the pressing strips 42 are smooth and free of burrs.

[0039] As Figure 5 and Figure 11As shown, one end of the arc-shaped pressing strip 5 is fixedly provided with an installation bearing plate 51. The installation bearing plate 51 is inserted into the bearing channel 24, and a limiting sliding hole 52 is opened on the installation bearing plate 51. A limiting bearing rod 25 is inserted into the limiting sliding hole 52, and the installation bearing plate 51 is hinged to the other end of the movable connecting rod 39.

[0040] As Figure 2 and Figure 12 shown, the limiting component is a movable stop strip 6. At both ends of the movable stop strip 6, matching stop strips 61 are symmetrically and fixedly provided. The matching stop strips 61 are located below the support inner strip 11. At the upper end of the matching stop strip 61, a support connecting column 62 is fixedly provided. At the upper end of the support connecting column 62, a limiting top block 63 is fixedly provided. The support connecting column 62 is inserted into the connecting matching hole 14, and the limiting top block 63 is inserted into the storage hole 13.

[0041] In addition, when the quenching bearing plate 2 is at the furnace mouth of the quenching furnace 1, the movable stop strip 6 is in contact with the moving support ring 23. At this time, the matching stop strip 61 is inserted into the retracted bottom groove 12. The lower end surface of the matching stop strip 61 is smooth and free of burrs, and its lower end surface is in contact with the inner wall of the moving support ring 23. As Figure 5 and Figure 7 shown, the reset component is a reset connecting strip 7. A limiting matching hole 71 is opened on the reset connecting strip 7. A limiting vertical rod 29 is inserted into the limiting matching hole 71. On the reset connecting strip 7 on both sides of the limiting matching hole 71, bending vertical plates 72 are symmetrically and fixedly provided. On the bending vertical plates 72, a reset bearing column 73 is fixedly provided. The reset bearing column 73 is inserted into the inclined reset frame 33. The surface of the reset bearing column 73 is smooth and free of burrs, and the reset bearing column 73 is in contact with the inner wall of the inclined reset frame 33. Before the reset connecting strip 7 moves upward, its lower end surface is in contact with the upper end surface of the quenching bearing plate 2. At this time, the reset bearing column 73 is at the lowermost end of the inclined reset frame 33.

[0042] When quenching the rocker arm, the rocker arm is sleeved on the supporting arc plate 27 through the shaft hole on the rocker arm, and the rocker arm is supported by the supporting arc plate 27. And the rocker arm is placed between the opposite pressing columns 37 and pressing strips 42. In this way, the limiting of the rocker arm can be realized under the action of the pressing columns 37 and the pressing strips 42. With the arrangement of multiple groups of pressing columns 37 and pressing strips 42, multiple rocker arms can be placed on one supporting arc plate 27. And under the limitation of the pressing columns 37 and the pressing strips 42, the rocker arms can be effectively prevented from contacting each other. When all the rocker arms on the quenching bearing plate 2 are placed, then the quenching bearing plate 2 is further pushed into the interior of the quenching furnace 1. As the quenching bearing plate 2 moves, the connecting carrier strip 3 on the quenching bearing plate 2 will contact the inner wall of the quenching furnace 1. In this way, under the limitation of the inner wall of the quenching furnace 1, the connecting carrier strip 3 will no longer move. As the quenching bearing plate 2 continues to move, the distance between the connecting carrier strip 3 and the quenching bearing plate 2 becomes smaller. Since the distance between the connecting carrier strip 3 and the quenching bearing plate 2 becomes smaller, under the action of the movable connecting rod 39, the two arc pressing strips 5 on the lower side of the same supporting arc plate 27 will move away from each other. As the arc pressing strips 5 move, the arc pressing strips 5 will contact the inner wall of the shaft hole of the rocker arm, and then the arc pressing strips 5 will tightly press against the inner wall of the shaft hole of the rocker arm. In this way, the preliminary fixation of the rocker arm can be realized under the action of the pressing force. And because the connecting carrier strips 3 are different, as the quenching bearing plate 2 moves, it will also drive the rocker arm to move towards the pressing column 37, and then the pressing column 37 will contact the side surface of the rocker arm. In addition, as the arc pressing strips 5 move away from each other and cooperate with the connecting rod 43, it will drive the movable bearing block 4 to move towards the quenching bearing plate 2, and then the pressing strip 42 on the movable bearing block 4 will contact the other side of the rocker arm. In this way, the pressing column 37 and the pressing strip 42 can clamp and limit the rocker arm from both sides, further playing a role in fixing the rocker arm and ensuring the firmness of the rocker arm during quenching. Moreover, when relative movement occurs between the quenching bearing plate 2 and the connecting carrier strip 3, the reset carrier column 73 on the quenching bearing plate 2 will move upwards along the inclined reset frame 33. Then, under the action of the reset carrier column 73, the reset connecting strip 7 will move upwards, preparing for the unlocking of the rocker arm. In addition, when the quenching bearing plate 2 further moves into the quenching furnace 1, it will finally cross the matching stop strip 61. That is, when the rocker arm is fixed, the moving support ring 23 will cross the matching stop strip 61 at this time. After the moving support ring 23 is separated from the matching stop strip 61, the matching stop strip 61 will lose its support at this time. Under the action of the self-weight of the movable stop strip 6, the movable stop strip 6 will move downwards, and then the matching stop strip 61 will protrude outside the retracted bottom groove 12. The end of the matching stop strip 61 away from the furnace mouth of the quenching furnace 1 contacts the moving support ring 23. In this way, under the action of the matching stop strip 61, the quenching bearing plate 2 will be limited and cannot move in the reverse direction.Furthermore, the firmness of the rocker arm during quenching can be ensured. After quenching is completed, push the movable stop bar 6 upward so that the mating stop bar 61 is inserted into the retracted bottom groove 12 again. In this way, the quenching carrier plate 2 can be in the unlocked state, and the quenching carrier plate 2 can be pulled outwards so that the support arc plate 27 on the quenching carrier plate 2 is outside the quenching furnace 1. Furthermore, the rocker arm is outside the quenching furnace 1, which is convenient for taking the rocker arm. When the quenching carrier plate 2 moves towards the furnace mouth of the quenching furnace 1, with the movement of the quenching carrier plate 2, under the action of the self-gravity of the reset connecting bar 7, the reset connecting bar 7 will move downward. In this way, with the cooperation of the reset carrier column 73 and the inclined reset frame 33, the connecting carrier bar 3 will be close to the inner wall of the quenching furnace 1 and will not move. In this way, the distance between the connecting carrier bar 3 and the quenching carrier plate 2 will become larger. As the distance between the two becomes larger, under the action of the movable connecting rod 39, the two arc-shaped tightening bars 5 on the lower side of the same support arc plate 27 will move towards each other and reset, and will no longer play a role in tightening the rocker arm. At the same time, the tightening column 37 and the tightening bar 42 will also release the rocker arm, and finally the unlocking of the rocker arm is realized. When the reset connecting bar 7 moves down to contact the quenching carrier plate 2, at this time, with the continuous movement of the quenching carrier plate 2, it will drive the connecting carrier bar 3 to move together, making the fixation and release of the rocker arm very convenient and fast, and can realize the synchronous fixation and release of multiple rocker arms, and the operation is simple.
